This book is informative, well designed and easy to use.
My only grizzle is a lack of information on what maker's marks, backstamps and signatures were used on various pieces which could perhaps help identification of other, similar items. I do realise this addition would bulk it up somewhat and I know there are other books with this information, but it would be quite nice to have it all in one place.
I bought this in hardback and, not being in true touch with all my faculties, bought it again later in paperback, which was a bit daft.
